After a rain-shower these drops remain on the leaves. A drop is defined as a small amount of liquid, which assumes a spherical shape when it is completely enveloped by free space or lying on a free surface. This form develops because the molecules of the liquid attract each other. Due to this cohesion, they arrange themselves as close as possible, resulting in the spherical shape. There are several proverbs making use of the word ‘drop’, like: 'one catches more flies with a drop of honey than with a barrel of vinegar ', in other words: a kind word has more impact than a long, angry tirade. Or something is just 'a drop in the ocean ': a remedy that is hardly sufficient to redress a problem.
